The goal of this clinical trial is to learn whether a physiotherapy-led exercise programme delivered during treatment before surgery (neoadjuvant therapy) for breast cancer can improve physical fitness, quality of life, and how well people cope with treatment. The study will also investigate whether blood and tumour markers, including microRNAs (small molecules that help regulate gene activity), together with information about the participant and the cancer itself (clinical information), can help predict how well patients respond to treatment. The main questions this study aims to answer are: * Does a structured physiotherapy-led exercise programme improve physical fitness, muscle strength, quality of life, and the ability to complete treatment? * Can blood and tumour markers, together with clinical information, help predict which patients will have the best response to treatment? Researchers will compare participants who receive the physiotherapy-led exercise programme with participants who receive standard care to determine whether the exercise programme improves physical and patient-reported outcomes. Participants will: * Receive standard treatment before surgery for breast cancer. * Be randomly assigned to either a 14-week physiotherapy-led personalised exercise programme or standard care. * Provide blood and tumour tissue samples for research. * Complete physical assessments and questionnaires about their symptoms, physical function, and quality of life during treatment. * Be followed throughout treatment, surgery, and follow-up to assess treatment response and other health outcomes.
Breast cancer is a heterogeneous disease with substantial variability in response to neoadjuvant systemic therapy despite advances in systemic treatment. Although pathological complete response (pCR) is an established surrogate marker of treatment efficacy in selected breast cancer subtypes, there remains a need for improved molecular and clinical predictors of treatment response, disease progression, and long-term outcomes. Circulating and tumour-derived microRNAs (miRNAs) have emerged as promising translational biomarkers because of their biological stability and potential to reflect tumour biology and dynamic changes during therapy. The IRELAND Trial is designed to prospectively integrate molecular, clinical, imaging, physiological, and patient-reported data collected throughout the neoadjuvant treatment pathway. The study aims to develop a comprehensive understanding of factors associated with treatment response and patient outcomes by combining biological specimen analysis with longitudinal clinical assessment. Blood and tumour tissue specimens will be collected at predefined time points for translational analyses, while radiological, pathological, and patient-reported outcome data will be collected prospectively using standardised assessment methods. Embedded within the translational cohort is a randomised controlled trial (CanReAct Trial) evaluating a structured 14-week physiotherapist-led personalised adaptive exercise programme delivered concurrently with standard-of-care neoadjuvant systemic therapy. Participants will be randomised to receive either the exercise intervention or standard care. The intervention is intended to optimise physical function during treatment and evaluate its effects on functional capacity, treatment tolerance, quality of life, and other patient-centred outcomes without altering oncological management. By integrating translational biomarker research with a structured supportive care intervention, the IRELAND Trial seeks to generate evidence that may improve prediction of treatment response while informing future personalised management strategies for patients undergoing neoadjuvant therapy for breast cancer.

A structured 14-week physiotherapist-led personalised adaptive exercise programme delivered concurrently with standard neoadjuvant systemic therapy. The intervention includes supervised and home-based aerobic and resistance exercise with progression tailored according to participant fitness, treatment tolerance and clinical status.
Estimated VO2max
Change in aerobic capacity (i.e. VO2max) as estimated from 6 minute walk test, following the physiotherapist-led intervention
Time frame: Baseline and 14 weeks (end of intervention)
Pathological complete response (pCR)
Pathological complete response (pCR), defined as the absence of residual invasive cancer in the breast and axillary lymph nodes at definitive surgery following completion of neoadjuvant systemic therapy.
Time frame: At definitive surgery following completion of neoadjuvant systemic therapy
Muscle Strength
Change in muscle strength measured using estimated one-repetition maximum (1RM) between baseline and completion of the intervention.
Time frame: Baseline and Week 14
Fatigue
Change in fatigue assessed using the Functional Assessment of Cancer Therapy-Fatigue (FACT-F) questionnaire. FACT-F is a patient-reported measure of cancer-related fatigue. Total scores range from 0 to 52, with higher scores indicating less fatigue (i.e. better outcome).
Time frame: Baseline and Week 14
Muscle endurance (lower body)
Change in muscle endurance measured using a squat test (as many squats as possible in one minute).
Time frame: Baseline and Week 14
Muscle endurance (upper body)
Change in muscle endurance measured using a push up test (as many correctly performed push ups in a row as possible).
Time frame: Baseline and Week 14
Participant retention rate
Proportion of enrolled participants who complete the 14-week physiotherapist-led exercise programme and remain in the study until completion of the intervention.
Time frame: Throughout the 14-week intervention
Adherence
Adherence to the physiotherapy intervention assessed by attendance rate and exercise log compliance.
Time frame: Throughout the 14-week intervention
Exercise-related adverse events
Incidence and severity of adverse events attributable to the exercise intervention.
Time frame: Throughout the 14-week intervention
Disease-free survival
Time from surgery to disease recurrence or death from any cause.
Time frame: Up to 10 years after surgery (or according to study follow-up)
Circulating and tumour microRNA expression
Identification of circulating and tumour microRNA expression profiles associated with pathological and radiological response to neoadjuvant therapy.
Time frame: Baseline, start of Cycle 3 chemotherapy, after completion of the 14-week physiotherapy programme, at surgery, 4 weeks post-surgery, and 12 months post-surgery (each cycle is 2-4 weeks).
Longitudinal circulating microRNA expression
Longitudinal changes in circulating microRNA expression during neoadjuvant therapy and follow-up.
